Paul B. Sigler ((1934-02-19)February 19, 1934 – (2000-01-11)January 11, 2000^[7][1]) was the Henry Ford II Professor of Molecular Biophysics and Biochemistry at Yale University.^[3][8] Major awards included membership in the National Academy of Sciences, HHMI Investigator status, and Guggenheim^[2] and Helen Hay Whitney Fellowships.^[5] He is noted for pioneering studies of Phospholipase A2 and trp repressor amongst many others.^[1]

Prior to coming to Yale, he was a professor at the University of Chicago.^[2] He received his MD from Columbia University in 1959 and his undergraduate degree from Princeton University in 1955.^[2] After briefly practicing medicine and working as a researcher for the NIH,^[5] he would go on to earn a second doctorate, a PhD, from Cambridge University at the Laboratory of Molecular Biology^[2] working under David M. Blow^[6] before moving to the University of Chicago.^[2]

A memorial plaque is located in front of the Bass Center for Structural Biology on Science Hill on the campus of Yale University. Yale has a Paul Sigler Memorial Prize for undergraduate research in Molecular Biophysics & Biochemistry.^[9] Yale also has sponsored Paul Sigler memorial symposia in the past.^[10] The Agouron Institute sponsored 12 Paul Sigler fellowships between 2000 and 2006.^[11]

Paul Sigler died on January 11, 2000, at New Haven, Connecticut, US, about a month before his 66th birthday.^{[citation needed]}
